Leg Wear

ABSTRACT

Leg wear includes a front having leg opening forming portions, and a back connected to the front having leg opening forming portions continuing to the leg opening forming portions of the front. The leg wear further includes thigh portion parts connected to the leg opening forming poritons of the front and back and formed into a cylindrical shape for inserting the thigh portions, The heights of the crests of the thigh portion parts are smaller than the curved depths of the leg opening forming portions, andthe widths of the crests are made larger than those of the curved portions of the leg opening forming portions, so that the thigh portion parts having a cylindrical shape int eh worn state are shaped to protrude forward relative to the front.

TECHNICAL FIELD

This invention relates to a leg wear such as underwear or sports wear, which are shaped to cover the thigh portions.

BACKGROUND ART

In most of the spats conventionally available in the market, the lower drum portion and the thigh portions are connected by one sheet of cloth, and its sportiness depends mostly on the stretchability of the material. Of those, the device to avoid the obstruction to the mobility of the thigh portions is the use of a highly stretchable material at the best.

In addition, the spats, which are given an excellent wearing feel by sewing parts of predetermined shapes, are exemplified by the sports wear of Patent Document 1. This sports wear supports the waist and the legs of the wearer reliably to protect the muscles and improve the athletic ability.

Patent Document 1: JP-A-2003-49304 DISCLOSURE OF THE INVENTION Problems that the Invention is to Solve

The aforementioned spats of the prior art have a basic pattern according to a standing position so that their individual devices are insufficient for following the bending practice of hip joints. The shape capable of matching better the motions of a body has been desired especially for sports events, in which the player is frequently required to bend forward or to squat down while raising the leg thereby to bend and stretch the hip joints severely.

In the spats of the prior art, moreover, the raw fabric at the buttocks is stretched and tensed to receive the pressure, and the thigh portions are held by the forces so that the body is exposed to the motion preventing resistance. In addition, there have also been proposed the products, in which the leg opening portions are changed to make and connect the lower trunk portion and the thigh portions of different parts. However, these products are insufficient for the stretchability or the motion followability. Likewise, the sports wear of Patent Document 1 cannot improve the motion followability at the time of bending and stretching the hip joints widely.

This invention has been conceived in view of the problems of the prior art thus far described, and has an object to provide a leg wear, which is smooth in the motions to bend and stretch the hip joints and suitable for exercise.

Means for Solving the Problems

According to the present invention, there is provided a leg wear comprising: a front having leg opening forming portions for curved leg openings, into which thigh portions are inserted; a back having leg opening forming portions connected to the front for covering buttock portions and having leg opening forming portions continuing to the leg opening forming portions of the front; and thigh portion parts connected to the individual leg opening forming portions of the front and the back for inserting the thigh portions thereinto, in which the curved crests of the leg opening forming portions of the front are positioned near the iliac spines whereas the lower end edges of the leg opening forming portions of the back are positioned near the lower ends of the buttocks; in which the heights of the crests of the thigh portion parts smaller than the curved depths of the front side of the leg opening forming portions, and in which the widths of the crests are made larger than those of the curved portions of the leg opening forming portions, so that the thigh portion parts having a cylindrical shape in the worn state are shaped to protrude forward relative to the front.

The length of the back from the waist portion to the crotch portion of the back is made larger than that of the front from the waist portion to the crotch portion, and no serious tension is applied to the back when the thigh portions are inserted into the thigh portion parts so that the thigh portions are protruded forward relative to the front.

The leg opening forming portions are shaped such that the hip hem lines are enveloped by the curved leg opening portions from the vicinities of the trochanters of the body through the vicinities of iliac spines to the vicinities of the crotch point and by curves bulging from the vicinities of the trochanters to the sides of the crotch point, and such that the leg opening forming portions contact closely with the hip hem portions.

The thigh portion parts are formed of one raw fabric having its two side edge portions folded back at the hem portions and connected in a laminated state over the leg opening forming portions of the front and the leg opening forming portions of the back, so that the overlapped raw fabrics of the thigh portion parts are made slidable relative to each other.

Advantage of the Invention

The leg wear of the present invention is formed into a stereostructure along the position of bent thigh portions and has little stretch in the raw fabric relative to the bending and stretching motions of the hip joints, so that the exercise can be done in the state of a low tension applied to the raw fabric. As a result, the resistance by the raw fabric is so low at the bending and stretching exercise that the wearer can enjoy smooth exercise while little burdening the body.

BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of this invention is described in the following with reference to the accompanying drawings. FIG. 1 and FIG. 2 show one mode of embodiment of this invention. The leg wear of this mode of embodiment is a shorts-type spats 10 extending from the waist to the intermediate portions of the thigh portions. The spats 10 are made of a raw fabric such as a stretchable fabric. The spats 10 are composed of a front 12 for covering the lower trunk portion from the front side to the two sides, a back 14 for covering the back side of the lower trunk portion, and a crotch portion part 16 for connecting the center of the lower end portion of the front 12 and the center of the lower end portion of the back 14. Moreover, a pair of thigh portion parts 18 formed into such a cylindrical shape as to cover the thigh portions are disposed in the openings which are formed by the front 12, the back 14 and the crotch portion part 16 so that the thigh portions may be inserted thereinto.

The shapes of the individual parts are described in the following. FIG. 3 shows the state, in which the spats 10 are developed. The front 12 includes a waist portion 20, and waist front side edges 22 which are cut substantially at right angles with respect to the waist portion 20 and near the iliac spines a at the thigh roots on the two sides of the waist portion 20. In the body front center sides of the waist front side edges 22, there are individually formed leg opening forming portions 24 for forming a pair of leg openings which are cut continuously from the lower end portions of the waist front side edges 22.

The leg openings provide openings for inserting the thigh portions thereinto when the spats 10 are sewn. At the back 14, too, leg opening forming portions 25 are formed in the back 14 from the side edges to the lower end edge, as will be described. The paired leg opening forming portions 24 are formed at such an inclination that they leave each other the longer as they come the closer to the waist portion 20 from the central position of the lower end portion of the front 12. The edge portion between the paired leg opening forming portions 24 provides a front crotch portion 26, at which the crotch portion part 16 is connected and which is formed of a slightly upward curve.

The back 14 includes an edge waist portion 28 widely opened generally into a V-shape, waist darts 29 cut into a V-shape at the center of the waist portion 28, and generally straight waist front side edges 30 extending generally at right angles with respect to the waist portion 28 away from the two ends of the waist portions 28. The waist front side edges 30 are made as wide as the waist front side edges 22 of the front, and made the wider as they leave each other the more from the waist portion 28.

Leg opening forming portions 25 directed toward the lower end of the back 14 are formed at the lower ends of the waist front side edges 30, and buttock darts 31 are cut in a V-shape on the body center side ends of the leg opening forming portions 25. A pair of leg opening forming portions 32 are formed on the body center side ends of the buttock darts 31. The leg opening forming portions 32 form the openings, through which the thigh portions are continuously inserted through the leg opening forming portions 24 of the front 12 when the spats 10 are sewn. Between the paired leg opening forming portions 32, there is formed a back crotch portion 34, to which the crotch portion part 16 is connected and which is formed into a slightly upward curve. Moreover, the length from the waist portion 28 of the back 14 to the back crotch portion 34 is made larger than that from the waist portion 20 of the front 12 to the front crotch portion 26. The leg openings, which are formed by the leg opening forming portions 24 and 25, are formed into such generally triangular shapes as have apexes located at the positions closest to the waist portion 20 and roundly curved.

The thigh portion part 18 includes a hem portion 36 formed of a slightly inward curve, and substantially straight thigh back side edges 38 which extend generally at right angles with respect to the hem portion 36 away from the two end portions of the hem portion 36. On the edge portion between the thigh back side edges 38 and opposite of the hem portion 36, there is formed a footed root portion 40 which has a crest 40 a bulging gently to the outer side. When the spats 10 are sewn, the footed root portion 40 is sewn to the leg opening forming portions 24 of the front 12 and the leg opening forming portions 25 and 32 of the back 14, and the crotch portion part 16 is also sewn to the opening which is continuously formed by leg opening forming portions 46. The edge portion of the crest 40 a of the footed root portion 40 is formed to have a length equal to that of the leg opening forming portions 24 of the front 12, and is sewn to the leg opening forming portions 24. Here, if the height of the crest 40 a of the footed root portion 40 to be attached to the leg opening forming portions 24 and 25 is designated by h1 and if the curved depth of the leg opening forming portions 24 and 25 is designated by h2, the depth h1 is smaller than the depth h2. If the width of the crest of the footed root portion 40 is designated by w1 and if the width of the curved portions of the leg opening front portions 24 and 25 is designated by w2, the width w1 is larger than the width w2 at the same positions to be sewn to each other.

The crotch portion part 16 is formed into such an hourglass shape elongated in one direction that its one longitudinal end portion is a front connected portion 42 to be connected to the front 12 whereas its other longitudinal end portion is a back connected portion 44 to be connected to the back 14. Both these connected portions are formed of bulging curves. The two longitudinal side edge portions of the crotch portion part 16 are the leg opening forming portions 46, which are so connected to the thigh portion parts 18 as to form portions of the foot openings and which are formed of inward curves. The crotch portion part 16 is made so wider by the leg opening forming portions 46 leaving each other the more toward the back connected portion 44 that the back connected portion 44 may be longer than the front connected portion 42.

Moreover, the length of a pattern of the leg opening forming portions 25 and 32 of the back 14 and the leg opening forming portions 46 of the crotch portion part 16 to the groin point is shorter than the length in the body length from trochanters b through the hip hem lines to the sides of the groin point.

In the method for manufacturing the spats 10 of this embodiment, the right and left buttock darts 31 and the waist darts 29 are sewn at first. Next, the front connected portion 42 of the crotch portion part 16 is attached to the front crotch portion 26 of the front 12. The right and left waist front side edges 22 and the waist front side edges 30 of the front 12 and the back 14 are sewn to each other. Moreover, the footed root portion 40 of the thigh portion parts 18 is sewn to the individual leg opening forming portions 24, 25, 32 and 46 connected in series. At this time, the portion of the angle made between the thigh portion back side edge 38 and the footed root portion 40 of one of the thigh portion parts 18 is positioned at the angle portion made between the back connected portion 44 and the leg opening forming portions 46 of the crotch portion part 16 already attached to the front 12. On the other hand, the angle portion made between the thigh portion back side edge 38 and the footed root portion 40 of the other thigh portion part 18 is positioned at the angle portion made between the back crotch portion 34 and each of the leg opening forming portions 32 of the back.

Next, the thigh portion backside edges 38 of one thigh portion part 18 are sewn to each other. Continuously, the back crotch portion 34 of the back 14 and the back connected portion 44 of the crotch portion part 16 are sewn to each other. Continuously, the thigh portion backside edges 38 of the other thigh portion part 18 are sewn to each other. Finally, the waist portions 20 and 28 and the hem portions 36 are subjected to finishing treatments and hemming treatments. Here, the sewing orders should not be limited to those described above but can be suitably changed.

The spats 10 thus sewn up have a stereostructure, in which the leg opening forming portions 32 of the back 14 extend round downward so that the thigh portion parts 18 formed cylindrical protrude obliquely forward and downward. In short, the basic stereostructure is made such that the wearer takes a forward slight slouching position shaped suitably for foot mobilities.

When the sewn spats 10 are put on, the leg opening forming portions 24 of the front 12: extend upward from the sides of the groin point and pass near the iliac spines a of the thigh roots of the legs; pass over the vicinity of the trochanters b above the thigh portion outer sides and turn; extend downward to the back side; and continue to the leg opening forming portions 32 of the back 14. The leg opening forming portions 32 of the back 14 arrive along the lower end portions of the buttocks at the vicinity of the groin point. The highest positions of the leg opening forming portions 24 are located near the iliac spines a. Moreover, the seams of the buttock darts 31 are so located slightly sideways of the highest positions of the buttocks as to pass vertically.

According to the spats 10 of this mode of embodiment, the stretchable material is used to retain the raw fabric for the buttocks, and the shape of the leg opening pattern is devised to retain the stereo-directivity of the raw fabric forward of the vicinities of the iliac spines a of the body, so that the wearer can receive less bending forward resistances at the hip joints and can practice with less fatigues. In connection with the buttocks, more specifically, the raw fabric is made sufficient for preventing any excessive fabric tension from being applied to the buttocks at the time of bending the hip joint, and the hip hem lines are shortened to prevent the hip hem lines from becoming misaligned. Especially, the spats 10 are given such a stereostructure as profiles the slightly slouching position of the wearer. In this position, the raw fabric does not establish a high tension so that it does not press the body. Moreover, the spats 10 suppress the load at the time when the wearer takes an action to bend more deeply. Moreover, the thigh portion parts 18 are given the stereostructure, in which they bulge forward. When the wearer raises the leg or squats down, as shown in FIG. 4 and FIG. 5, the raw fabric can exert less resistance to the thigh portions so that the wearer can take exercise easily. Moreover, the raw fabric follows the motions of the body so that it can reduce the brushing of the wear. Moreover, the back 14 is made vertically longer than the front 12 so that no serious tension is applied to the back 14 when the wearer raises the leg or squats down, as shown in FIG. 4 and FIG. 5. This enables the wearer to take smooth exercise without any slip-up of the back 14.

In addition, the seams of the buttock darts 31 pass the positions moved slightly sideways from the highest positions of the buttocks so that they can provide the raw fabric sufficient for following the motions of the buttocks in the bending and stretching actions. Moreover, the seams are. less stretchable than the surrounding raw fabric, so that they can eliminate the resultant wearing uncomfortable feeling.

Here, this invention should not be limited to the aforementioned mode of embodiment but may be modified into the individual parts shapes, as shown in FIG. 6. The leg wear of this embodiment is also directed to the spats including backs 48 and 49 symmetrically halved from each other, and a waist part 50 at the waist portion. Moreover, the buttock darts of the aforementioned mode of embodiment are eliminated, and the shape of the buttocks is formed into the stereostructure by the paired darts between the vicinities of the upper end edge centers of the backs 48 and 49 and the lower portion of the center of the waist part 50. As a result, it is possible to acquire effects similar to those of the aforementioned mode of embodiment and to improve the hold feeling of the waist portion by using a highly tense raw fabric for the waist part 50.

As shown in FIG. 7, on the other hand, the buttocks may also be shaped into a stereostructure by eliminating the aforementioned buttock darts and by using the paired darts of the waist front side edges 22 and 30 between the front 12 and the back 14. Moreover, the hip hold and hip-up effects can be given by using a highly tense material in the side edge portions of the front 12.

Moreover, another mode of embodiment may have the shape of a development shown in FIG. 8. In this mode of embodiment, the aforementioned buttock darts and waist darts can be connected into one switching line of the front 12 and the back 14. As a result, it is possible to acquire effects similar to those of the aforementioned mode of embodiments and to give more clearances for the buttock portions in the natural shape.

Moreover, the thigh portion parts 18 may also be formed of one raw fabric into the raw fabric shape which has the end edge of the hem portion 36 as the axis of symmetry, as shown in FIG. 3, and which is folded back on the axis of symmetry of the hem portion 36. In the folded state, moreover, the two footed root portions 40 or the two side edge portions of the hem portion 36 may be overlapped and sewn to the leg opening forming portions 24 of the front 12 and the leg opening forming portions 32 of the back 14. In this case, the raw fabrics of the thigh portion parts 18 overlapped are made slidable relative to each other.

As a result, even in the continuous bending and stretching actions, as shown in FIG. 5, the thigh portion parts 18 can be prevented from slipping upward of the thigh portions, thereby to provide a better wearing feeling.

In addition, it is possible to change the hem length and the waist position and to find various applications such as wears for sports such as ball games or swimmings or underwear. The shapes of the individual parts can also be modified according to the kinds of sports and the body shapes of wearers.
